[David Allen]

IIRC the base timing is 8 degrees BTDC with bypass disconnected, engine idling.

+AD4- Well... for unforeseen events leading up to the lack of spark in my 
+AD4- Mazda truck and the unavailability of any form of standard parts being 
+AD4- Japanese and all (lol whatever the reason is) I decided to try to fix my 
+AD4- Heep ASAP... so... I spliced the tan/black wire.... set the timing to 
+AD4- zero... at zero it runs like crap.   Plugged it back in... and the 
+AD4- timing advanced... however what should the timing advance to on a '88 
+AD4- Chevy S10 Pickup with the 2.5L?  For it still runs like crap and idles 
+AD4- funny (maybe idle is just set too low? dunno its late to think about it 
+AD4- anymore)  Any other ideas as to what I would check (sensor wise) as to 
+AD4- why it'd be idling funny...  so yeah
